GAS-HEATER.

To all whom it may concern.

Be it known that I, ALcoRN REo'roR, of the city, county, and State of New York, have invented a new and useful Improvement in Gas-Heaters, of which the following is a full, clear, and exact description.

My invention relates to improvements in gas heaters which are used more especially for heating the air, as distinguished from hydro-carbon burners used for ranges, furnaces and the like.

The object of my invention is to produce a-simple form of apparatus in which ordinary illuminating gas may be burned but mingled with unusually large proportions of atmospheric air, and in which the heater may be made especially attractive.

A further object is to produce a structure which can be made in many difierent designs, but in which the atmosphere surrounding the heater is not vitiated to the slightest degree, but on the contrary the heater serves to ventilate the room in which it is located. The heater can be used as a substitute for gas logs, gas radiators, and other heating devices, and it can be made in radiator form or in any preferred design, as will appear from the specification which follows. a

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar reference characters indicate corresponding parts in all the views.

Figure 1 is a broken sectional elevation more or less diagrammatic, of the apparatus embodying my invention, and Fig. 2 is a cross section on the line 22 of Fig. 1 looking in the direction of the arrow.

My invention utilizes one or more Bunsen burners or tubes 10, having air inlet openings 10 and which can be of any usual or preferred type, and generally these are arranged in parallel and fed from a common gas supply pipe. The Bunsen tubes have their upper extremities 12 perforated so that the mingled gas and air will burn through the perforations as usual, but the particular formation of the Bunsen tube or any part of it does not enter into the princi le of my invention, as any preferred style 0 Bunsen burner can be used. The Bunsen tubes, however, extend preferably airtight, but not necessarily so, into pipes 13, in such a way that the air inlet opening 10 Specification of Letters Patent.

of the bunsen is not inclosed in said pipes 13 and these pipes connect with an expanded part or hood 15 of an exhaust pipe 16 which connects with a suitable exhaust fan 17 located at the end of the pipe, and the fan as illustrated, is driven by a motor 18, which can be of course any means of propulsion. The pipe 16 is provided with a common form of shutter or slide 19 through which air may be admitted if desired, and-it is also provided with a drop pipe 20 having a similar shutter 21. The object of these shutters is to open the pipe 16 so that a better ventilation may be had in the room if desired, but the shutters 19 need not be opened when the exhaust fan is in operation. If, however, the exhaust fan should be out of use, then the shutters 19 can be opened so as to provide a natural draft, and the heater can be operated until the fan can be again repaired or set in motion. The drop pipe 20 can also be dispensed with if desired. It will be noticed that with these shutters the fan may be operated and the device used as a ventilator, even though the heater be not in use, and when the heater is in use the quantity of air admitted to the pipe can be controlled so that ventilating purposes may be better subserved. It will also be noticed that the drop pipe 20 can be connected with another stove or gas lamp, or simply used as a ventilator and that any desired number of these branch pipes may be used.

lVhen the Bunsen tubes are lighted, the motor 18 is started and the air is exhausted from the pipe 16 and from the pipes 18. Obviously there may be but one of these pipes 13, in which case the pipe 16 is simply an extension thereof. WVhen the exhaust fan is started and the heater or burners lighted, the products of combustion are withdrawn through the pipe 16, and not only this, but a greatly increased flow of oxygen is thereby stimulated and the burners generate a tremendous heat, dependent of course on the power of the fan. When thus heated they do not vitiate the air, because the gases pass away through the pipe 16, but they do cause the pipe 13 to become red hot and to glow beautifully. These pipes can be made of metal, earthenware, fire-clay, or any suitable material which will sufficiently resist heat, and it will be seen that the pipes may be made in radiator form, in

the form of a gas log, or in any preferred style, the only essential thing being that they connect with an exhaust pipe so that they may be exhausted, and the connection with the pipe may be air tight or not as desired.

I have shown a single heater connected with the pipe 16, but it will of course be understood that any desired number of these heaters may be included in a single pipe system so that several heaters on the floor of a building may connect with one pipe which has the means for exhausting it, and that all air is exhausted by a single exhaust fan. This is so evident that I have not shown the several heaters so connected, but such a heater might, for instance, be connected with the branch pipe 20.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. In a gas heater, the combination of a Bunsen burner, a heater surrounding said Bunsen burner and so adapted that substantially no air can enter the heater except through the bunsen, and a pipe connected with, and having means for exhausting the air from, said heater.

2. In a gas heater, the combination of a Bunsen burner, a heater surrounding said Bunsen burner, and so adapted that substantially no air can enter the heater except through the bunsen, a pipe connected with said heater, and an exhaust fan at the outlet end of said pipe.

3. In a gas heater, the combination of a main pipe having a regulable air inlet, an exhaust fan located near the discharge end of said pipe, a heater connected with said pipe, and a Bunsen burner extending into said heater.
